AI generated property description:
The ServiceNow property glide.db.instant_alter.enabled determines whether the Now Platform uses MariaDB INSTANT ALTER algorithms when modifying database table schemas. Its default value is true, which allows schema changes such as adding columns to be executed instantly without requiring a full table rebuild. This improves performance and reduces downtime during schema updates but applies only to operations supported by MariaDB’s instant alter feature. Setting the property to false forces the platform to use traditional alter methods, which may take longer and impact system performance. Administrators typically leave this enabled to optimize schema management, except in cases where compatibility or troubleshooting requires reverting to non-instant operations.
